A drive unit for an electric vehicle has an outrunner motor. The outrunner motor has: a motor housing; a rotor disposed in the motor housing; a stator disposed in the motor housing and radially inward of the rotor, the stator having a plurality of stator coils; and an output shaft disposed radially inward of the stator, the output shaft being driven by the rotor, the output shaft and the rotor rotating together about an output shaft axis defined by the output shaft. The vehicle also has an inverter electrically connected to the plurality of stator coils, the inverter having an inverter housing connected to the motor housing; and a fan disposed between the stator and the inverter housing, the fan being configured to draw air between the motor housing and the inverter housing and to supply this air into the motor housing.
